Custom made by Nigel Stockbridge of Errington Mandolins in the UK. Mahogany body, maple neck and fretboard, single humbucker pickup with volume control, strings-through bridge design. Nigel has a workshop at his home in North Yorkshire, and says he's ready to make Erringtons again after a three-year hiatus. These will cost £249 for a basic model, including a gig bag, and will be made from cherry rather than mahogany. He sells direct, so check out his Web site.
